GPU L9: Memory

00:00:09.216,00:00:12.216 Rajesh Pandian M: yes 00:00:12.083,00:00:15.083 Prasoon Mishra CS20S028: Yes sir 00:00:15.504,00:00:18.504 Piyush Avinash Chincholikar cs20m045: Good morning 00:03:38.125,00:03:41.125 Shouvick Mondal: stream is a channel in the bus? 00:07:28.606,00:07:31.606 SANKET NEEMA cs19m055: here the global memory we talking abot is Ram of gpu? 00:08:01.832,00:08:04.832 Sheera Shamsu CS20D001: Why registers are called as Register files? 00:11:55.903,00:11:58.903 Shouvick Mondal: block, thread coordinates are in higher dimension major, right? 00:28:02.032,00:28:05.032 Rigved Sah cs20m053: Is it global memory and L2 cache is share across sm and l1 cache is avilable for each sm? 00:29:03.055,00:29:06.055 Jeeva Keshav S ee20s057: does GPU also follow similar coherence protocols like CPU? 00:33:05.413,00:33:08.413 Parth S. Shah ee17b059: Since the registers are shared across the SM, are the registers allocated core-wise before hand or are they allocated thread wise as a thread begins execution? 00:40:12.711,00:40:15.711 Shashank Rahul Mishra cs20m058: lossy lossless 00:40:13.961,00:40:16.961 Dhruv Gopalakrishnan ae17b004: lossy/lossless? 00:41:38.219,00:41:41.219 Jeeva Keshav S ee20s057: sir, where does this compression take place? 00:44:15.016,00:44:18.016 Jeeva Keshav S ee20s057: okay sir 00:45:15.639,00:45:18.639 Prasoon Mishra CS20S028: It's an overhead. So if it's zero it's better 00:45:25.375,00:45:28.375 Sumit Negi cs20m067: To avoid stalls 00:50:44.692,00:50:47.692 Shreyas Jain cs20m063: pc 00:53:31.315,00:53:34.315 Akash Haridas ae17b020: is latency hiding similar to time multiplexing? 00:55:03.798,00:55:06.798 SANKET NEEMA cs19m055: Sir can you please reexplain bandwidth improvement, recompute than store + fetch ? 00:56:08.773,00:56:11.773 Shagnik Pal ee17b147: Sir you told we can control data in scratchpad memory. Do we mean that we can control what data goes where in the L1 cache? 00:56:30.732,00:56:33.732 Akash Haridas ae17b020: ok, thank you sir 00:58:07.342,00:58:10.342 SANKET NEEMA cs19m055: okay sir.
